Abstract:
The pest causes severe damage to stored food grains in many parts of the world. Though effective synthetic pesticides have a number of drawbacks including high cost, non-biodegradability and adverse effects on humans and the environment prompting farmers to seek out a more powerful and economically feasible alternative. There are several recent advances were developed for stored grain pest management which may involves the use of PVOC, nanotechnology, inert dusts, sands, silica aerogel and ionizing radiation. The control of insect pest is done by using different techniques such as by use of Insect Pheromones, Insect Growth Regulators (IGRs), Cultural Control and Microbial Control. Plant volatile organic compounds (PVOC) minimizes the application of synthetic insecticides in stored grains pest management and exhibit their effect on insects through their several charateristeics such as their toxic effect, repellency, fumigant, growth inhibitor, suppression of reproductive behavior, chemosterilants, antifeedant or feeding deterrent and reduction fertility. Nanotechnology offering active ingredients for stored grain pest management over the world. Nanoparticles have a larger surface area and circulate more freely in insects and making them unique harness chemicals. There are various nanoparticles such as essential oil nanoparticles, silver, aluminum and zinc oxide, diatomaceous earths, silicon dioxide and nanosilica (nanobiopesticides) used for stored grain pest management. These recent methods may provide a solution to the problems associated with health risks, availability, costs and resistance of synthetic pesticide and used for stored grain pest management.
